摘要
研究了有压缩和驱动项的含时谐振子系统的时间演化．通过适当选取厄密不变量，得到含时谐振子系统的量子态时间演化的封闭解及该系统的时间演化算符，给出产生压缩态的条件，得出驱动项不影响系统压缩态的结论．
Abstract In this paper are discussed the time evolution and squeezed states of a time depedent oscillator system. We obtain closed formulas for the time evolution of quantum states and the evolution operator of the system by selecting proper Hermitian invariant operator. We derive the condition generating squeezed states and obtain that the drive part does not influence the squeezed states of the system.
